Class for caching/grabbing a webpage?

[alfredn]

Do not refer me to PEAR or Curl please (or any other large libraries ;]). I'd like to know if anyone knows of or has a class that will cache a webpage and place it in a folder as needed.

Thanks in advance

I can code you a class that uses a TCP socket to connect, query, and cache at a specified location.
Would be in the range of 30 to 45 lines of code, would that work for you?

If you create it, send me a copy, i'm very intrested how you do this all in 30-45 lines :)

Lol, sure, I'm going to zip it and throw the link up. And it's a total of 35 lines, not including comments on usage. I've tested this and it works on my Linux PHP 5.2.1

I'm not sure but I think classing changes from 4 to 5. . . That and sockets need to be turned on (I think on is default. . .)

Usage is simple:


include('webCache.php');
$WC =& new webCacher();
$WC->cacheURL("http://www.google.com/", "test.html");


The page is then saved in the same directory as "test.html" (headers and all, though a simple function can easily be written to remove them if not wanted), if you changed the "test.html" to "../cachedPages/newCache.php" it will be saved in that directory under that file name. Simple enough I think =]

Let me know if there's problems: http://bubblecoder.com/webCache.zip

Very simple way...
function cache($site, $relative_location)
{
return file_put_contents($relative_location, file_get_contents($site), LOCK_EX);
}

You can use a simple if to check if it already exists.

Heh, forgot all about file_get_contents(), my mind jumped straight to sockets xD
Geuss that's a more reasonable method than mine if you don't need to mod headers =]

Thanks guys but well, I probably should have been specific; im looking for something that'll save the images as well, and if possible, any links on the page that go to images (save those as well). I code myself so file_put_contents has been tried. But I appreciate it anyhow :]. I probably could write something, but tbh, I really don't want to lol.
